ASSAY AND EXPRESSION OF SUPEROXIDE DISMUTASE ON EXPOSURE TO ENDOSULFAN AND FENVALERATE

K. SUNEETHA

Abstract

Superoxide dismutase is an essential enzyme for the survival of oxygen utilizing organisms. In the present study, freshwater fish Labeo rohita was exposed to two pesticides, i.e., Endosulfan (35% EC) an organchlorine and Fenvalerate(20% EC) a synthetic pyrethroid. The LC50 values determined for endosulfan and fenvalerate at 24 h were 0.6876, 0.4749 μgL-1 respectively. The 1/10th of 24 h LC50 of both the pesticides was selected as sublethal concentrations. The fish were exposed to sublethal concentrations for 15 days the activity and expression of Superoxide dismutase in different tissues was reported.
